摘　　要：使用Bordoni型的仪器在声频范围内研究了铁镍基金属玻璃的低温含氢内耗,并研究了退火处理对内耗的影响。结果表明低温含氢内耗是Snoek 型弛豫,并观察到了反常模量亏损和反常弛豫强度现象,提出τ缺陷增强 Snoek 弛豫模型解释了反常弛豫强度现象。The internal friction of hydrogen at low temperature and the annealing effect on it have been studied in iron-nickel based metallic glasses using Bordoni-type apparatus. The result shows that the internal friction of hydrogen at low temperature is snoek-like relaxation and the abnormal modulus defect and the abnormal relaxation strengh have been observed. The model of enhancement of τ-type defect to snoek-like relaxation is proposed to explain the abnormal relaxation strengh.
